What are the “8717 servos” of 2019?
I remember these were the hot cyclic servos to have for quite some time a while back. What are you guys flying nowadays that offer the speed/torque/hv capabilities of the trusty 8717s?

Servos have come a long way since the 8717. The higher spec HV 8717s were 230 in-oz, .06 second servos and came in at around $200. Those were killer specs for their time. Some would suggests it's all you need even today.

Today $100, 1/2 the price, gets you a killer servo and nearly twice the torque + better speed.

If you're insistent on spending $200 the list of choices is nearly endless. I own a lot of MKS X8 servos and like them but there are so many other good choices. I'm sure others will suggest servos that are working well for them.

There are a whole bunch of options starting at about $60 to over $250 per unit.

I like KST for budget options and Futaba BLS for high end. ProTek and Xpert servos are awesome too. DFA/JR has awesome servo options in their new 8915s. They even have 12v servos with insane torque, over 1000oz. Many choices.
